运用轨道部件的振动加速功率谱密度函数与轮轨噪声功率谱密度之间的关系，分析了轨道结构弹性对降噪的作用。 - Abstract : to against the fact of the commercial available white noise generators are very expensive which is not good for general operations , a simple and effective limited band white noise generator is design . the generator is using the feature of dual polarity transistor , i . e . , the power spectrurn density of particulate noise is not related to frequency in very wide band and close to white noise . the concrete circuit is also given
文摘:针对市售白噪声发生器价格昂贵，不利于一般场合使用的问题，介绍利用双极性晶体管散粒噪声功率谱密度在非常宽的范围内与频率无关，属白噪声这一特性，设计了一种简捷、有效的限带白噪声发生器，并给出了具体电路。 - In the paper , the esd stressing tests for n - channel mosfets are performed , and main electrical parameters , 1 / f noise spectrum and its time series are monitored during the test . it is found that the 1 / f noise changes much more sensitive to the esd latent damage than the electrical parameters , at the same time , similarity coefficient also changes more quickly especially for smaller w / l devices
通过对mos器件的静电应力试验，同时监测试验过程中器件的电参数、 1 / f噪声功率谱密度以及由1 / f噪声的时间序列提取的相似系数变化，发现1 / f噪声对于静电应力引起的损伤要比电参数的变化敏感得多。
